Please bookend your old 2000's with the two 2000c's. That was what was recomended to me with a stack of 9 of them.

""I also looked at this route. I'm no network expert (know enough to be dangerous) and haven't spent much time on this yet. I scanned the connections on the local network, but missed finding the inverter as a connected device (unless I'm missing some point)"" OK so remember that you Wireless Router is a switched device , with the wireless on one port and the other 4 posts all switched. Therefore if you sniffed traffic on one of the wired ports you will see only the broadcast traffic and not all traffic between the ports. Also why I unpack the old 10Mbps hub to do packet captures on, as that acts as a singe braodcast domain, will all traffic available on all ports for all device connected on it. This holds true unless you are doing wireless traffic sniffing on a wireless port of say a laptop, as wireless on its own is again like a hub, a single broadcast domain (yes yes, and hardly any security). Oh how you long for the days when ckies was a network ninja!

Sadly Modbus and most IOT protocols were defined for industrial application within closed communities, and therefore did not consider the overhead of encryption. Now you also know that the FieldBus and Modbus traffic that Eksdom sends around from many many places in AssZainia is clear text. Commands send to SCADA systems remains in the clear as well. The City of Adelaide in AsStralia as had a small matter of a knowledgeable employee, opening the valves if the affluent treatment plant to the river. The untreated matter cased a bit of a stink... Some day we will see such abuse noted next to the Wet Coal stories by Eksdom. << Vitek Boden used computer equipment, two way radios, and his laptop to hack into the Maroochy Shire Council waste management system, and released millions of litres of raw sewage into the local environment after his job application was rejected by the council.>>

That statement of "It send raw data over the internet to the central server once a minute - which is good enough for me." has me interested, and I should try this myself. If you can install Wireshark AND find an effective way to tap the line (data interception) than you will see the raw packets going out on your link. You might have to ask a IT networking type to help you with the data capture and then the snipping of the parts that includes the metrics that goes to SEMS portal. The logical layout will look like this : Inverter Wireless -> Wireless Router ->HUB Hub splits the traffic to Internet Router and to PC running Wireshark. Just a warming. You will see all of the traffic that is "clear text " on Wireshark (No do not tell me about your privacy concerns, I deal with that from 8 - 4 every weekday!) If you do this on Linux you might find a way to do local logging of that data, or buy a new Wifi chip and load your own redirect addressing into in, rather than to Sems Portal. I have my old chip at hand from Replus if there is someone that wants to do that data set compare of the config data within the EPROM.

A set of battery brackets which allows vertical stacking of the Pylon battery unit. 1 set required per additional battery added. 3 sets available to a good home. Postnet to Postnet shipping can be arranged. R1150 for all 3 sets.

To help out on why the phone app will not work when you are not within your own home (and own Wifi cover). The app makes a direct Wifi connection to the inverter. It could be that you connected the inverter AP to your Wifi AP as well. Irrespective, you will need to emulate being at home if you wanted the phone app to functions. For that you will have to configure your WiFi Router to accept an inbound VPN, and load a VPN client on your phone, to connect to your router. Your phone will then believe that it is inside the home WiFi coverage, but keep in mind that some other apps may not what to play so well at that time, like Outlook Email or WhatsApp, depending on your routing skills and VPN functionality. In the end I will default to using SEMS portal and live with having to configure things when at home. (the bad part is you may be traveling and an outage needs attention. do you have a spare tablet or phone so you can talk the kids through the needed steps (not the wife = female partner). 🙂 PS I live in the IT security world!

I would like to have a chat. Also have an ES5048 - older version, plus Pylontech US2000 P LI... And just received the Ezconverter. Not sure how to wire and power it!
